My friend's house

I went for a walk for the first time in two weeks yesterday evening. (I had avoided exercising because my asthma got worse.)

I passed by the place where T-chan's house used to be. Her house was   demolished about a few months ago, and now a new house was being built there. I noticed the house owner's name on the sign board was not her parent's. 

I remember she had a older sister, so maybe the new owner's name is her sister's husband's or T-chan's husband's. Or maybe it is a complete stranger's name. If so, what happened to her parents?

T-chan and I went to the same schools -- from kindergarten to high school. I didn't know her well until high school and we weren't particularly close, but she was always kind and cheerful and I liked her.

I haven't seen her since we graduated from high school. I wonder where she is now and what she is doing...
